[0028] Working principle: Printed circuit board, also known as printed circuit board, is the provider of electrical connection of electronic components. Printed circuit board is mostly represented by "PCB". Its design is mainly layout design. The main advantage of using circuit board is that it greatly reduces wiring and assembly errors, improves the level of automation and production labor rate. According to the number of layers of circuit board, it can be divided into single-sided board, double-sided board, four-layer board, six-layer board and other multi-layer circuit boards. Among them, PCB board production is drilled by laser, and the PCB board is fixed by a jig plate for laser drilling. The surface of the PCB board is drilled through the laser laser. After starting the servo motor 2, it can drive the circular gear 3 to rotate synchronously. After the circular gear 3 rotates clockwise, it drives the two racks 6 meshing with it to move toward each other. The two moving blocks 5 are respectively active at one end of the corresponding parallel rod 4. Since the bottom of the pad 8 is connected to the rack 6 by the abutment rod 7, as the rack 6 moves, the pad 8 also moves synchronously, which drives the two pads 8 to move toward each other, so the two pads 8 can be adjusted The distance between the two pads 8 increases the workstation for laser drilling of the PCB board and improves the efficiency of the laser drilling jig. After the laser drilling of the PCB board is completed, a lot of debris will be accumulated on the surface of the pad 8. At this time, the PCB board placed on the surface of the two pads 8 is taken out manually, and then the staff can start the micro motor 16. After starting the micro motor 16, the moving block 11 is driven to move back and forth at one end of the screw rod 10, so that the bottom surfaces of the plurality of cleaning strips 14 are respectively scraped with the debris accumulated on the surface of the pad 8. Sweeping makes it easy to scrape the debris to the sides of the two pads 8, saving the time of the staff to manually adjust the position of the brush body. The outer surface of the moving block 11 fits the inner wall of the drilling seat 1, and the moving block 11 can move smoothly left and right under the rotation of the screw rod 10. The scraping plate 13 is connected to the moving block 11 by an L-shaped plate 12. Therefore, as the moving block 11 moves, the two scraping plates 13 also move, and the bottom surface of the cleaning strip 14 can scrape against the surface of the pad 8, so as to facilitate the scraping of the accumulated debris.
